There's actually mail on Saturdays?
I get very little personal mail. I mostly get the ever dreaded bills, most of which do come during the week. I rarely get more than two birthday/Christmas cards and all my bills are paid online. At work, we're used to getting a heavier load of mail on Monday's because our offices aren't open on Saturdays. So in essence, having no Saturday service won't really affect my life all that much.
